[0002] During the drilling process, if the drill bit breaks inside the workpiece, it is difficult to remove the broken drill bit, especially for deeper holes, which are difficult to remove with ordinary tools. Currently, an extractor is often used to remove the drill bit that is broken inside the workpiece. The extractor usually consists of two parts, including a drill rod and a screwdriver bit. First, the drill rod needs to be used to drill the broken drill bit, and then the screwdriver bit is inserted into the drill hole to use the resistance to remove the broken drill bit. However, the drill rod and screwdriver bit currently used are usually split structures. When using them, it is first necessary to select the corresponding drill rod according to the diameter of the drill bit. After drilling, the corresponding screwdriver bit needs to be selected again, which is inconvenient to operate. Therefore, the present application proposes a composite extractor.
